McCarthy*,a,b, James Fansona, Rebecca Bernsteina,b, David Ashbyc, Bruce Bigelowa, Nune Boyadjiana, Antonin Boucheza, Eric Chauvina, Eduardo Donosoa, Jose Filgueiraa, Robert Goodricha, Frank Groarka, George Jacobya, Eric Pearcea aGMTO Corporation, 451 N. Halstead St., Suite 250, Pasadena, CA 91107, USA bCarnegie Observatories, 813 Santa Barbara St., Pasadena, CA 91101, USA cLarge Binocular Telescope Observatory, Tucson AZ ABSTRACT The Giant Magellan Telescope Project is in the construction phase. Production of the primary mirror segments is underway with four of the seven required 8.4m mirrors at various stages of completion and materials purchased for segments five and six. Development of the infrastructure at the GMT site at Las Campanas is nearing completion. Power, water and data connections sufficient to support the construction of the telescope and enclosure are in place and roads to the summit have been widened and graded to support transportation of large and heavy loads. Construction pads for the support buildings have been graded and the construction residence is being installed. A small number of issues need to be resolved before the final design of the telescope structure and enclosure can proceed and the GMT team is collecting the required inputs to the decision making process. Prototyping activities targeted at the active and adaptive optics systems are allowing us to finalize designs before large scale production of components begins. Our technically driven schedule calls for the telescope to be assembled on site in 2022 and to be ready to receive a subset of the primary and secondary mirror optics late in the year.

A new generation of Extremely Large Telescopes (ELTs) with >20m primary mirror diameters, operating with next-generation adaptive optics systems that deliver diffraction-limited image quality, will provide transformational new research capabilities. ELTs will enable major advances in several research topics within the Cosmic Frontiers theme including the nature of dark matter; unprecedentedly precise measurement of the cosmic expansion rate; the physics of compact object mergers identified by gravitational wave events; and tests of General Relativity's description of gravity in close proximity to the supermassive black hole in the center of our Galaxy. The US ELT Program, a collaboration between NSF's NOIRLab and the Thirty Meter Telescope and Giant Magellan Telescope projects, proposes to complete construction of a bi-hemispheric system that will provide US researchers with unique ELT coverage of the whole sky and a powerful suite of instruments.

Wide Field Astronomical Image Compensation with Multiple Laser-Guided Adaptive Optics
Invited Paper Wide field astronomical image compensation with multiple laser-guided adaptive optics Michael Hart, N. Mark Milton, Christoph Baranec,* Thomas Stalcup, Keith Powell, Eduardo Bendek, Don McCarthy, and Craig Kulesa Center for Astronomical Adaptive Optics, The University of Arizona, Tucson, AZ 85721 *California Institute of Technology, 1200 E. California Blvd., Pasadena, CA 91125 ABSTRACT We report closed-loop results obtained from the first adaptive optics system to deploy multiple laser guide beacons. The system is mounted on the 6.5 m MMT telescope in Arizona, and is designed to explore advanced altitude-conjugated techniques for wide-field image compensation. Five beacons are made by Rayleigh scattering of laser beams at 532 nm integrated over a range from 20 to 29 km by dynamic refocus of the telescope optics. The return light is analyzed by a unique Shack-Hartmann sensor that places all five beacons on a single detector, with electronic shuttering to implement the beacon range gate. Wavefront correction is applied with the telescope's unique deformable secondary mirror. The system has now begun operations as a tool for astronomical science, in a mode in which the boundary-layer turbulence, close to the telescope, is compensated. Image quality of 0.2-0.3 arc sec is routinely delivered in the near infrared bands from 1.2–2.5 μm over a field of view of 2 arc min. Although it does not reach the diffraction limit, this represents a 3 to 4-fold improvement in resolution over the natural seeing, and a field of view an order of magnitude larger than conventional adaptive optics systems deliver.

Biographical Memoir COPYRIGHT 2007 NATIONAL ACADEMY OF SCIENCES WASHINGTON, D.C. Photograph by Mount Wilson and Los Campanas Observatories HORACE WELCOME BABCOCK September 13, 1912−August 29, 2003 BY GEORGE W . P RESTON ORACE BABCOCK’S CAREER at the Mount Wilson and Palomar H(later, Hale) Observatories spanned more than three decades. During the first 18 years, from 1946 to 1964, he pioneered the measurement of magnetic fields in stars more massive than the sun, produced a famously successful model of the 22-year cycle of solar activity, and invented important instruments and techniques that are employed throughout the world to this day. Upon assuming the directorship of the observatories, he devoted his last 14 years to creating one of the world’s premier astronomical observatories at Las Campanas in the foothills of the Chilean Andes. CHILDHOOD AND EDUCATION Horace Babcock was born in Pasadena, California, the only child of Harold and Mary Babcock. Harold met Horace’s mother, Mary Henderson, in Berkeley during his student days at the College of Electrical Engineering, University of California. After brief appointments as a laboratory assis- tant at the National Bureau of Standards in 1906 and as a physics teacher at the University of California, Berkeley, in 1907, Horace’s father was invited by George Ellery Hale in 1908 to join the staff of the Mount Wilson Observatory (MWO), where he remained for the rest of his career.

Manufacture of 8.4 M Off-Axis Segments: a 1/5 Scale Demonstration
Manufacture of 8.4 m off-axis segments: a 1/5 scale demonstration H. M. Martina, J. H. Burgea,b, B. Cuerdena, S. M. Millera, B. Smitha, C. Zhaob aSteward Observatory, University of Arizona, Tucson, AZ 85721, USA bOptical Sciences Center, University of Arizona, Tucson, AZ 85721, USA ABSTRACT We describe the requirements for manufacturing and maintaining alignment of the 8.4 m off-axis segments of the Giant Magellan Telescope’s primary mirror, and a demonstration of the manufacturing techniques on the 1.7 m off-axis primary mirror of the New Solar Telescope. This mirror is approximately a 1/5 scale model of a GMT segment. We show that the stressed lap polishing system developed for highly aspheric primary and secondary mirrors is capable of figuring the GMT segments and the NST mirror. We describe an optical test with a null corrector consisting of a tilted spherical mirror and a computer-generated hologram, and derive accuracy requirements for the test. The criterion for accuracy of low-order aberrations is that the active support system can correct any figure errors due to the laboratory measurement, with acceptably small forces and residual errors. Keywords: telescopes, optical fabrication, optical testing, aspheres 1. INTRODUCTION The Giant Magellan Telescope (GMT, Figure 1) is a 22 m telescope whose primary mirror is made of seven 8.4 m circular segments.1 The segments are lightweight honeycomb sandwich mirrors of the type used for the MMT, Magellan telescopes, and Large Binocular Telescope (LBT). This design makes use of a proven concept for the mirror and supports, and mature manufacturing technology.

Support for Site Testing of the European Extremely Large Telescope: Precipitable Water Vapour Over La Silla†
Support for site testing of the European Extremely Large Telescope: precipitable water vapour over La Silla† Richard R. Querel*a, Florian Kerberb, Gaspare Lo Curtob, Joanna E. Thomas-Osipc, Gabriel Prietoc, Arlette Chacónd, Omar Cuevasd, Diana Pozod, Julio Mar´ınd, David A. Naylora, Michel Curéd, Marc S. Sarazinb, Carlos Guiraob and Gerardo Avilab aInstitute for Space Imaging Science, University of Lethbridge, Canada; bEuropean Southern Observatory, Garching, Germany; cLas Campanas Observatory, La Serena, Chile; dGrupo Astrometeorolog´ıa, Universidad de Valparaiso, Chile ABSTRACT The European Southern Observatory (ESO), the Institute for Space Imaging Science (ISIS) and the AstroMete- orology group at the Universidad de Valparaiso collaborated on a project to understand the precipitable water vapour (PWV) over the La Silla Paranal Observatory. Both La Silla and Paranal were studied with the goal of using them as reference sites to evaluate potential E-ELT sites. As ground-based infrared astronomy matures, our understanding of the atmospheric conditions over the observatories becomes paramount, specifically water vapour since it is the principle source of atmospheric opacity at infrared wavelengths. Several years of archival optical spectra (FEROS) have been analysed to reconstruct the PWV history above La Silla using an atmospheric radiative transfer model (BTRAM) developed by ISIS. In order to better understand the systematics involved, a dedicated atmospheric water vapour measurement campaign was conducted in May 2009 in close collaboration with Las Campanas observatory and the GMT site testing team. Several methods of determining the water col- umn were employed, including radiosonde launches, continuous measurements by infrared radiometers (IRMA), a compact echelle spectrograph (BACHES) and several high-resolution optical echelle spectrographs (FEROS, HARPS and MIKE).
